Automatic Metal Door Frame Roll Forming Machine for Steel and Aluminum Profiles

Automatic Metal Door Frame Roll Forming Machine  is a specialized automation equipment that efficiently processes metal coil (steel or aluminum) into precision door and window frame profiles through continuous cold bending process. The core principle is to sequentially pass the metal strip through a multi component roller, gradually bend it through each pass, and finally obtain the desired cross-sectional shape.

Equipment Introduction：

This device is an automated production line that integrates multiple functional modules, and its standard workflow is as follows:

1.Uncoiler: Place coiled metal materials (steel coils, aluminum coils, etc.) on the uncoiler.

2.Leveling: Using a leveling device to eliminate internal stress in metal strips, ensuring their flatness and preparing for precise forming.

3.Roll Forming: This is the core process. The metal strip is gradually and continuously bent into the designed profile section through multiple passes (usually 12 to 18 or more) of forming rollers.

4.Punching&Cutting: After continuous forming, the equipment can punch installation holes, lock holes, etc. on the profile according to the program, and cut them into preset lengths.

5.Output: The final product is output through a conveyor platform to complete production.

Main application scenarios：

The profiles produced by this equipment are widely used in the fields of construction and industry

• Building doors and windows:
used for producing various steel or aluminum door and window frames, including fireproof door frames, anti-theft door frames, etc.

• Curtain wall and partition:
It is an important equipment for producing building curtain wall support structures and light steel keel partition skeletons.

• Industrial and commercial facilities:
widely used in the manufacturing of doors, windows, and frame structures in industrial plants, warehouses, supermarkets, hotels, and other places.

• Other profiles:
By replacing the rollers, this equipment can also be used to produce various metal profiles such as furniture metal frames and HVAC pipe supports.
